I have just had solar panels inatalled. After installation, does my usage appearing in the AGL app represent the gross usage (i.e. energy generated from the solar panels plus energy supplied by the grid) or the net usage (i.e. energy supplied by the grid only without counting energy generated by the solar panels)? I do have SEMS Portal installed for reading information from the inverter. Do I need to install a separate app for the smart meter (not the AGL app which I have already installed) to read information from the smart meter?
